Line 1:
Line 1: − In [[physics]], a '''frame of reference''' is the point from which an observer views a system. There are two types of reference frames, inertial frames and non-inertial frames.+ − − [[Inertial reference frame|Inertial frames]] are frames that have linear and angular [[acceleration]] equal to zero. [[Newton%27s_Laws_of_Motion|Newton's laws of motion]] only apply in inertial frames, although in many cases they are a close enough approximation in a non-inertial reference frame (for example, the earth is not an inertial reference frame as it is both rotating about its own axis and orbiting the sun and therefore accelerating). − − Non inertial frames are frames that have either angular or linear (or both) accelerations that are not equal to zero. [[Newton%27s_Laws_of_Motion|Newton's laws of motion]] do not apply in these frames. Objects observed from within appear to violate [[Newton%27s_Laws_of_Motion|Newton's laws of motion]]. [[Fictitious forces]] such as the [[Coriolis effect]] and centripetal acceleration can be explained through the use of non inertial reference frames. Both are caused by the acceleration of the reference frame itself. − − [[Category:Physics]]
